Today a circuit will be built to make a two-tone doorbell. We will use two ICs, one CD4060 which is an oscillator with a 14-step binary counter and a CD4001 that implements 4 NOR ports. The first integrated will divide …

We will present several ways to use buttons as inputs for a circuit. The state of a button is the most basic form of binary logic it is open or closed, however when assembling a circuit you have to keep …
